Application November 27, 1940; Serial No. 36:7,452

(Cl. ice- 9) 2 Claims.

This application relates to shingles or covering plates and particularlyto thck shingles and to a method of laying such shingles.

When thick shingles are laid, as on a wall, side or roof, and theshingles are of conventional shape, a serious objection is found due tothe formation of pockets where shingles overlap. Even if such pockets be`on the down side of the shingles, as they are laid on a sloping roof,rain will be pulled into such pockets to leak through due to the suctionthat exists when rain is running down a slo-ping roof.

To overcome the form-ation of such pockets, when thick shingles areused, I have developed a novel method of laying shingles of old butnonconventional shape so as to avoid the formation of pockets.

such shingle shape and shingle laying method are shown in the appendeddrawing and described in the following specification.

In this drawing,

Fig. 1 shows a group of shingles laid down in the manner of theinvention;

Figs. 2 and 3 are sections as if on lines 2--2 and 3-3 of Fig. 1;

Fig. 4 shows a single shingle;

Fig. 5 shows the shingle of Fig. 4 in conjunction with a second laidshingle;

Fig. 6 shows the shingles of Fig. 5 in conjunction with a third laidshingle;

Fig. 7 shows the shingles of Fig. 6 in conjunction with a fourth laidshingle.

Referring to the drawing and particularly to Fig. 4, it will be seenthat a shingle to be laid down according to the invention may be of theshape shown. Thus, it will have a corner notched at a, a projectingcorner b, edges c and d acljacent to the notch a, edges e and f opposingthe notch a, and other corners g and h.

In the laying of the shingles, :a notch a of one shingle receves aprojecting corner b of a neighboring shingle, which will thus be in thesame plane as the first named shingle; by positioning a projectingcorner of one shingle into a notch of another, the two shingles may thusbe made to lie in the same plane and this, coupled with a regular planor layout of shingles, avoids the formation of pockets for the purposesabove described.

The method of laying shingles will now be described, with referenceparticularly to a regular group, namely, a group of shingles selectedfrom the center of the entire roof, so as to avoid reference to specialproblems which arise at edges of the roof, or at intersections, or atchimneys or stacks, etc.

Fig. 7 shows a regular group which comprises four shingles of the shape`of Fig. 4, laid down as follows:

In the regular group, shingle No. 4 will be considered as the shinglefirst laid down.

shingle No. 5 is then laid down over shingle No. 4 to form the layoutshown in Fig. 5. Notch opposing edge e of shingle No. 5 will lay overthe notch a and the notch adjacent edge d of shingle No. 4.

A third shingle No. l will now be laid'down. Notch a of shingle No. lwill receive the projecting corner b` of shingle No. 5. Notch adjacentedge c of shingle No. l will lay over notch opposing edge f of shingleNo. 4. shingles I and 5 will be in the same plane which is one planeforward or above the plane of shingle No. 4.

shingle No. 2 is now laid down to complete the regular group of fourshingles and will be found in a third plane which is one plane forwardof the plane of shingles Nos. l and 5. Notch adjacent edge c of shingleNo. 2 will be laid down over notch opposing edge f of shingle No. 5.Notch opposing edge e of shingle No. 2 will lay down over notch adjacentedge d and notch a of shingle No. l. Corner g of shingle No. 2 will laydown over corner b of shingle No. 5 and over corner h of shingle No. 4,with corner h of shingle No. 5 being exposed by notch a of shingle No.2.

For the shape shingle shown in Fig. 4, edges e of shingles Nos. 2 and 5will be in the same line and edges c of shingles Nos. I and 2 will be inthe same line.

To illustrate how a larger number of shingles may be laid down,reference should be had to the layout shown in Fig. 1. The order oflaying down the eight shingles shown in Fig. 1 is as follows:1-8-4-5-6-l-2-3, care being taken to align the various edges of theshingles in accordance with the layout plan above described for theregular group of four shingles shown in Fig. 7.

Now having described a shingle layout, which when laid down properlywill avoid the formation of pockets, despite the thickness of theshingles, reference should be had to the cl-aims which follow for adetermination of the invention.

I claim: v

1. A wall embodying a plurality of thick shingles or covering plateseach having a projecting corner diagonally across from which is a cornernotched for receiving a projecting corner of one neighboring coplanarshingle, every regular group of four shingles occupying three planes andbeing made up of a first laid shingle, a second laid shingle having anotch-opposing edge lad the notched corner as well as over anotch-adja.-`

cent edge of the third laid shingle, with the second and third ladshinglesbeing coplanar, and with the first and fourth laid shinglesbeing in separate planes, between which is the plane of the second andthird shingles.

' 2.`. A method of laying a regular group of four thick shingles orcovering plates, each having a corner notched, a projecting corner, twoedges adjacent the notch, and at least two edges opposing the notch,which last two edges help define the projectng corner of the singlewhich comprises (a) laying down a shingle, (b) laying a second shingleover the first, with a notchopposing edge of the second shingle layingover the notch and. a notch-adjacent edge of the first shingle, (c)laying a third shingle over the first, with its notch receiving theprojecting' corner of the second shingle, and with a notch-adjacent edgelaying over a notch-oppcsing edge of the first shingle, and (d) laying aourth shingle over the first three laid shingles, with a notch-adja-'cent edge laid over a notch-opposing edge of the second shingle, and anotch-opposing edge laid over a notch-adjacent edge of and the no-tch ofthe third shingle, and a corner lai-d over but spaced from a 'corner ofthe first shingle and laid over but engaging the projecting corner ofthe second shingle, with the second and third lad shngles beingcoplanar, and with the first and fourth laid shingles being in separateplanes, between which is the plane of the second and third shingles.
